At least 25 road homers but fewer than 50. Could they have hit 50 homers playing only on the road?

Donn Clendenon hit 25 home runs (HR) on the road in 1966 playing for the Pittsburgh Pirates...Now I will examine batters who hit at least 25 HR on the road but did not hit 50 HR for the season to determine whether playing only on the road they could have reached 50 HR.Click link to view details; tab "25 HR road but < 50 total" is sorted by total HR...Clendenon homered every 90.7 at bats (AB) at home, every 12 AB on the road: 87 percent better on road. Percent of home HR: 11.Clendenon hit only three HR at home for a total of 28, the lowest of any of the 59 seasons with at least 25 HR on the road but fewer than 50 HR for the season.

Please read the post above in its entirety before continuing. This post is really a continuation.

48 different players, including both named Frank Thomas, hit at least 25 HR on the road but fewer than 50 HR in a season; it was done 59 times. Eight players who did it it multiple times:

Two of the top five above were right handed batters in Pittsburgh: Clendenon and the first Frank Thomas, who held the Met record for homers in a season with 34 from 1962 through 1974. The surprise above is Jason Giambi. Not that he hit 29 HR on the road but that he did it playing his home games in Yankee Stadium, a park which contradicts its reputation for rewarding lefty home run hitters more than expected.9 times a batter in this group had a HR rate at least 50% better on the road (Rate % Dif), led by Clendenon at 87%:

When the road HR rate is applied to total AB 39 of 59 increase to at least 50 HR led by Larry Walker in 1997 with Colorado zooming from 49 to 62, the only batter to reach 60. Donn Clendenon was not among the 39 but he improved from 28 to 48.Only one player dropped: Babe Ruth 1929 from 46 to 44.6. Ruth's AB were skewed: 219 home, 280 road. Homers: 21 home, 25 road.Joe DiMaggio finally overcame the vast left and center field of Yankee Stadium in his day, improving on his 1937 46 to 53.Albert Pujols had the most shots, hitting on two of four:
2004 46 to 56
2006 49 to 50
2009 47 to 48
2010 42 to 47.Hank Aaron reached 50 on 2 of his 3:
1957 44 to 51
1962 45 to 52
1963 44 to 48.Lou Gehrig got there: 1930 from 41 to 51.Roger Maris not quite: 1960 from 39 to 49.Ted Williams jumped from 38 to 51 in 1957 to go with his .388 batting average.Both players named Frank Thomas got to 50, the elder from 35 in 1958, the younger from 40 in 1995.Nine moved up to at least 55 HR (HRonlyRoad), including Mark McGwire in 1987, his rookie season, from 49 to 56.

All but Ruth improved with 3 of 7 reaching 50 HR. Yankee Stadium might not have been the HR haven some had thought for lefty batters. DiMaggio was the only righty.In addition to Maris hitting 61 (31 road) in 1961 and teammate Mickey Mantle hitting 54 (30 road), the old American League might have had two more over 50. The road rate applied to Maris in 1961 would have reduced him from 61 to 59. Mantle would have remained at 54.
